Common situations and problems in campus and classroom management
In the past campus management and the use of classroom equipment, there were often the following problems:
(1) There are so many devices that it is difficult to realize intelligent perception, control and management.
(2) It is too complicated to manually push down the projection curtain, switch on and off the lights, adjust the air conditioning temperature and switch on and off the exhaust fan, which not only wastes the actual teaching time, but also greatly reduces the classroom experience;
(3) There is no clear data to check and analyze the usage and energy consumption of all kinds of equipment, which is not conducive to energy saving and improvement.
According to the actual needs of classroom scenes, Zhou Shun Intelligent has launched a smart classroom Internet of Things scheme, which is dedicated to the intelligent upgrade of classroom scenes.
Internet of Things Scheme for Intelligent Classroom
Based on the advantages of Zigbee technology, Zhou Shunzhi can realize intelligent control of electrical equipment such as lighting, fans, air conditioners, curtains, audio-visual teaching equipment and smart door locks in classroom scenes with the help of Zigbee3.0 gateway and embedded Zigbee module, saving personnel management costs, improving equipment management efficiency and creating intelligent teaching/learning experience for teachers and students.
1, scene mode
Situational strategy is a set of actions, which is simple and efficient to operate. If you start a day's study period in the morning, the air conditioner and exhaust fan will be turned on automatically in advance to improve the air environment in the classroom; Students enter the classroom, access control is opened, and music is played; When the teacher is in class, the projection is turned on, the projection curtain is put down, and the desk lamp is turned off or dimmed. Through scene switching and system configuration, enter the preset scene mode with one button. Such as "classroom scene", "classroom scene", "multimedia scene" and "audio-visual scene" can be customized.
2. Intelligent access control system
Intelligent access control supports administrators to conveniently enter personnel access records and master access control status and alarm information in real time. In addition, the intelligent access control system combined with face recognition function effectively guarantees the security and safety of school classrooms.
3. Classroom equipment management system
Real-time status display of equipment: it can display the working status of equipment (such as whether the light is on or off) and the fault display of equipment (whether the switch is faulty) in real time. Independent control function of equipment: each equipment can be controlled and managed through the equipment management system. Controlled equipment includes: air conditioner, projection controller, computer, fluorescent lamp, curtain, energy and environmental equipment, professional equipment, access control and door lock, etc.
4. Intelligent environmental monitoring system
Monitoring and adjustment of classroom environment. Through the temperature and humidity sensor and air quality sensor, the real-time monitoring of classroom temperature and humidity and air quality can be realized, and the environmental data can be sent back to the server and cloud platform in real time. Through strategic deployment and equipment linkage, open fresh air, humidifiers, fans and other equipment to adjust the classroom environment. Realize the intelligent control of classroom environment and ensure that the teaching environment is in a comfortable state.
5. Intelligent energy-saving system
Through the Internet of Things platform, you can remotely control the classroom equipment, switch the equipment, set the scene mode, and customize the switching equipment during the time period to avoid the equipment being turned on and idle for a long time during non-teaching time. At the same time, the platform can display and analyze energy consumption data, clearly understand the electricity consumption of various regions and types of equipment, and realize energy conservation and emission reduction.
6. Intelligent power safety system
The intelligent switches, intelligent plugs and temperature control panels in the classroom are embedded with Zigbee modules, which can remotely query the electricity consumption data of air switches, such as line voltage, leakage current, line power, line current and switch status, set up automatic detection of leakage protection function, and remotely manage all power line switches in the area, and set up timing switches in groups freely.
Advantages of Internet of Things Scheme in Smart Classroom
1, with wide equipment coverage and convenient deployment.
Support most manageable devices in the classroom, including dozens of IOT sensors and controllers such as multimedia, air conditioners, switches, energy-saving sockets, lighting, curtains, environmental monitoring, security, electricity, etc. The scheme adopts ZigBee wireless fidelity, which avoids the traditional wiring problem, and can quickly complete the deployment of the hardware environment of the Internet of Things through simple upgrade, which reduces the hardware deployment cost and construction difficulty and greatly accelerates the deployment speed.
2. Smart and convenient use
The scene and timing strategy of the Internet of Things can be flexibly customized to realize automatic batch and timing control of equipment. Intelligent automatic adjustment can be realized according to temperature, humidity and light intensity.
3. Energy conservation and emission reduction
Real-time detection of energy consumption of key energy-consuming equipment can realize the transparency of energy consumption information and scientific management of energy consumption.
